Because the guy who made it possible isnt really interested in this game anymore
Actually it appears that he is back to being interested, he made another texture importer and said he was working on a Caw Injector with the possibility of renders. --- I don't always post on message boards, but when I do, I prefer GameFAQs
Yeah, the buzz on CAWS.ws is that they're coming. Looks like they're working on taking the wrestler bio pics from WWE.com and potentially filtering them so they match the in-game screen select pics. We shall see.
if you are following his facebook he has answered this.
essentially THQ decided rather than fix one of the 657656745 bugs they added checksums galore to the CAS files(why they are so damn big) so he cant seem to get texture renders for retail most likely because apparently blocking this hack was on the top of the priority list. but blocking hacks that put freeze moves in the moveset was not a priority.
THQ and their troll logic.
there is of course the fact that THQ could be smart and embrace the modding community instead of trying to circumvent it and block it.
